Try it now — no download

Point it at a folder. See your library in seconds.

This runs entirely inside this browser tab. Nothing is uploaded, nothing is downloaded, and nothing is saved anywhere — your files never leave your computer, and everything disappears the moment you close or reload this tab.

Nothing uploaded Nothing downloaded Nothing saved — close the tab, it's gone No account needed

We'll scan for STL, OBJ, 3MF, and G-code files — the first 10 found. Your browser reads them locally to generate thumbnails; none of it is ever sent over the network.

Folder picker not working?

This preview is deliberately basic — real thumbnails and colours where the file has them, capped at 10 files, no STEP conversion. The full app scans your whole library with no cap, plus STEP support, manual recolouring, duplicate detection, tags, and a print queue.
